qtPyGraphEdit V00 pre-alpha

Download the zip, extract to a folder of your choice.
This is a Windows build. If you want other platforms, the source should build quite easily from the Readme instructions

A "rolling chassis" of the graph editor.
Most functions work reasonably.
Deletion has a bug, and leaves ghost lines.
Print scaling is badly out - use export - SVG rather.

Anything else, feel free to open an issue. I can't promise when I will look at them, but extra eyes are always welcome!
